This is a simple formatting trick I use to make regular expressions more readable. The secret? Break them into multiple lines. To achieve this, format the regex as an array of strings and then concatenate the array into a single regex string. Example # Compare this example, written in a single line: const FILTER_REGEXP = /(?<name>blur|brightness|contrast|grayscale|hue-rotate|invert|opacity|saturate|sepia)\((?<value>-?\d*(?:\.\d*)?)(?<unit>\w*?)\)/g; with the multi-line version:…

One-on-one meetings with your manager are one of the most valuable tools you have for career growth, problem-solving, and unlocking new opportunities.

At OpenAI, we have long believed image generation should be a primary capability of our language models. That’s why we’ve built our most advanced image generator yet into GPT‑4o. The result—image generation that is not only beautiful, but useful.
4o image generation is a new, significantly more capable image generation approach than our earlier DALL·E 3 series of models. It can create photorealistic output. It can take images as inputs and transform them.
I'm using Signal more now and as it's fully end-to-end encrypted, if something goes wrong with your phone or you lose it, you will lose your entire message history.

Customers to gain more flexibility through open banking payments
Data scientists use different Jupyter notebooks every day — ranging from disposable ones for quick tasks to those shareable with clients. Over time, more and more notebooks accumulate, making it increasingly difficult to reuse them in whole or in part. To mitigate this problem and make the most relevant pieces of code quickly accessible to every data scientist, we developed…

Frontier reasoning models exploit loopholes when given the chance. We show we can detect exploits using an LLM to monitor their chains-of-thought. Penalizing their “bad thoughts” doesn’t stop the majority of misbehavior—it makes them hide their intent.
